Abstract
Description
Technical Field
[0001] The utility model relates to the field of connectors, in particular to a variable-diameter signal female terminal. Background Art
[0002] High current charging and discharging is the development trend of new energy electric vehicles in the future. With the high current, the heating of the plug terminal is a huge problem. There are two ways to solve the heating problem. The first is to strengthen the heat dissipation to make the working temperature below the dangerous threshold; the second is to reduce the contact resistance of the conductive parts. When the resistance is reduced, the temperature will naturally drop. In order to ensure a small contact resistance, it is necessary to increase the contact area between the plug terminal parts. The plug terminal generally includes a male pin and a current-carrying female terminal. The head of the male pin contacts the rear end of the current-carrying female terminal to transfer the current. If the contact area needs to be increased, the size of the socket on the current-carrying female terminal must be increased to completely wrap the male pin insertion part. In this way, its manufacturing cost increases significantly, and the friction between the male pin and the current-carrying female terminal increases sharply. It also needs to be aligned when inserted, which causes many inconveniences in daily maintenance.
[0003] Based on the above problems, someone invented a Chinese utility model patent named multi-contact high current terminal with patent number 2019217558901. After testing, the above solution has the following defects:
[0004] The above scheme is a female terminal structure with the same diameter at both ends. When using, the user cannot plug two male terminals with different diameters into each other to conduct the signal; therefore, it cannot be adapted to products that require the signal male terminal to change its diameter. Utility Model Content
